BALING-MACHINE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed July 9, 1914. Serial No. 849,935.

T 0 all whom it may concern Be it known that I, FRED A. LUNDAHL, acitizen of the United States, residing at Moline, in the county of RockIsland and State of Illinois, have invented certain new and usefulImprovements in Baling- Machines, of which the following is aspecification.

My invention has reference to baling presses, the chief purpose thereofbeing to provide a machine of the class named for baling waste paper,rags, and other refuse material, which machine will be simple,efficient, and durable, and will be formed of metal throughout.

In the drawings, Figure 1 is a front elevation of my machine with thereceiving door open. Fig. 2 is a side elevation thereof. Fig. 3 is ahorizontal section through the rear plate of the machine. Fig. 4; is aview of the lower part of the machine with the door open.

My device embodies a receptacle formed of side plates 1 and 2, a rearplate 3, a base plate 4:, and a door 5 hingeably connected to theplate 1. All of said parts are formed of sheet metal, the plates 1 and 2being braced at top and bottom by means of outwardly projected flanges 6and 7, and the rear plate 3 is reinforced by ribs 8 formed verticallytherein by pressing outwardly a portion of the metal of said plate. Thefloor 4 is given additional strength by being projected upwardly a shortdistance within the receptacle, and the door 5 is provided withreinforcing ribs 9, formed by bending the metal outwardly.

The door 5 is formed with a hinged upper section 10, the downwardmovement of which is limited by braces 11 pivotally supported in thelower part of the door. The lower part of the door is held in closedposition by means of a frame 12 pivoted to the side plate 2, and held inplace by a latch 13 pivoted to the door 5. Mounted on the body of thepress is a cover 6 and a pair of angle bars or plates 14 between whichlatter are outer and inner brackets let and 14 respectively in which isrotatably supported a shaft 15, upon which is secured a pinion 16.Secured on the plates 14, which additionally constitute a topreinforcement for the press, is a guide 17, in which a rack 18 hasvertical movement, the teeth of said rack being in mesh with the teethof the pinion 16. On

the lower end of the rack 18 is secured a plunger 19, which upon thedownward movement of the rack is caused to exert a pressure upon thecontents of the receptacle to force the same into compact space. Fixedon the shaft 15 is a ratchet wheel 20 adapted to be engaged by a pawl 21on the inner end of a hand lever 22, pivotally supported on said shaft.On the outer end of the shaft 15 is a hand wheel 23, by operation ofwhich the shaft 15 may be rotated in a direction to raise the rack 18.To rotate said shaft in theopposite direction and move said rackdownwardly, the pawl 21 is turned over into engagement with the wheel20; and the lever 22 moved downwardly. lVhen the rack 18 is in elevatedposition, it may be held therein by means of a trip 2-1, pivoted in theguide 17, and adapted to engage the teeth of the rack. By turning saidtrip in the opposite direction such rack may be locked from up wardmovement to hold the contents of the receptacle in compressed shapeuntil the same have been suiliciently bound. In operation the upper part10 of the door is dropped downwardly, and the plunger 19 raised to itshighest point, (see Fig. 1), leaving an opening for the introduction ofthe material into the machine. lVhen the receptacle is filled to such aheight as the opening will permit, the upper part of the door is closedand secured by hook 25, or other suitable means. The plunger 19 is thenlowered, compressing the contents of the machine into shape for binding.

The binding operation may be accom plished by means of suitable wires orcords passed through openings 26 in the rear plate of the machine andalong channels formed by plates 27 fixed to the plunger 19. The floor 4is similarly provided with channels formed by plates 28 along which thelower ends of the wires may be passed. Previous to this operation thedoor 5 has been opened, and the ends of the wires may be brought together in front of the bundle and fastened together. The plunger 19 isthen raised and. the bale removed from the machine.

To further reinforce the side plates and prevent them from bending orbuckling under the strain of the compressing oper ation, I provide onthe outer face of each of said plates a channel plate 29, extending fromtop to bottom thereof, and provided near its middle part With two ormore notches 30 which permit a limited amount of contraction to thestrips 29 when the machine is under pressure.

My machine being formed of metal throughout, the parts thereof beingrigidily united wherever possible, and the weaker partsthereof beingreinforced fully, the maximum amount of efficiency is obtained with theminimum amount of material. A machine is thereby produced which is notonly of comparatively light weight, but which possesses all thenecessary points which tend toward durability.

lVhat I claim as my invention, and desire to secure by Letters Patent ofthe United States, is:

1. A baling press, comprising a receptacle formed of sheet metal sideplates, provided at top and bottom with outwardly projecting flanges; aback plate formed of sheet metal provided with vertical reinforcing ribsintegral therewith; a sheet metal door hinged to one of said side plateshaving transverse integral ribs, and provided with a pivoted uppersection adapted to drop clownwardly; a plate mounted on said receptacle;a rack vertically movable in said plate; a plunger on the lower end ofsaid rack; a shaft rotatably mounted on said plate; a

pinion on said shaft in mesh with said rack; a ratchet wheel on saidshaft; a hand lever pivoted on said shaft and provided with a pawladapted to engage said ratchet wheel; a hand wheel fixed on said shaft;and means for locking said rack from upward or clownward movement asdesired.

2. In a device of the class named a receptacle comprisin a pair of sideplates, provided at top and bottom with outwardly projecting flanges; arear plate provided with vertical reinforcing ribs formed integrallytherefrom; a door hingeably connected with one of said side plates, andprovided with a pivoted upper section; transverse reinforcing ribs insaid door; a frame pivotally attached at the free side of said door; alatch pivoted to said door and adapted to engage said frame; andreinforcing angle plates on the outer faces of said side plates theoutwardly projecting portions of said angle-plates being provided with aplurality of notches.

In testimony whereof I ailix my sigi'iature in presence of twowitnesses.
